Figure 5From: The C-terminal domain of the Bloom syndrome DNA helicase is essential for genomic stabilityWestern analysis of stable transfected cell lines expressing mutant BLM alleles. A. Whole cell lysates (15 μg total protein) from uninduced and induced cells were resolved on 4-12% SDS polyacrylamide gels and transferred to PVDF membranes. The bound complexes were detected with ECL reagents and exposed to x-ray film: 1) GFP-BLM+Tet, 2) GFP-ΔN1 no Tet, 3) GFP-ΔN1+Tet, 4) GFP-ΔN2 no Tet, 5) GFP-ΔN2+Tet. 6) GFP-ΔN3 no Tet, 7) GFP-ΔN3+Tet, 8) GFP-ΔN4 no Tet, 9) GFP-ΔN4+Tet. B. ECL western analysis of whole cell lysates: 1) GFP-BLM+Tet, 2) GFP-K695T no Tet, 3) GFP-K695T+Tet, 4) GFP-ΔH1 no Tet, 5) GFP-ΔH1+Tet, 6) GFP-ΔC1 no Tet, 7) GFP-ΔC1+Tet, 8) GFP-ΔC2 no Tet, 9) GFP-ΔC2+Tet. The positions of molecular weight standards are indicated to the left. Filters were reacted with α-GFP and goat α-mouse secondary conjugated with horseradish peroxidase. The bound complexes were detected with ECL reagents and exposure to x-ray film. C. Identical filters were reacted with α-GFP and goat α-mouse secondary conjugated with alkaline phosphatase. The fluorescent ECF product was visualized with a Molecular Dynamics Storm. The fluorescent image was quantitated using Imagequant. The values were normalized to normal GFP-BLM expression.Back to article page
